<br />15.0 Preliminary Cosl Estimales <br /> <br />Some preliminary cost estimates are provided in two categories: 1) estimated <br />costs to implement cloud seeding programs in the areas identified with good potential but <br />without any current programs and 2) estimated costs of possible llpgrades to existing programs. <br />A few clarifications are needed. <br /> <br />. These are preliminary estimates and are subject to revision. <br />. Some of the improvemcnts to existing programs may not be implemented but other <br />upgrades may be suggested as alternatives by the clients or contractors of these programs <br />\vhich would change the cost estimates. <br />. Some of the new programs may not be implemented. again changing the cost estimates. <br />. Recommendations contained in scction 18 propose that design studies be conducted for <br />cach potential new target area in ordcr to customize cloud seeding activities to that area. <br />As a consequcnee the scope of the programs and therefore their costs may change. <br />. Another recommendation in section 18 is that an evaluation component be built into the <br />dcsign of the ne\v programs. Thesc preliminary cost estimates include 15% of the <br />estimated operating budget for new programs for evaluation purposes. Existing programs <br />already have on-going evaluations built into their designs. As a consequence. no <br />additional funds are proposed for evaluations of existing programs. <br />. Some of these preliminary cost estimates contain capitalization costs for equipment (e.g.. <br />remotely controlled ground generators). As a consequence. the operating costs ofsomc <br />programs could drop in future years. <br />. These figures do not include the costs of operating the existing programs in Colorado <br />and Utah. <br />. Thesc figures do not include the costs of operating a program over the west slopes of the <br />\Vind River Range in Wyoming since the Wyoming Water Development Commission <br />has funded a five ycar program which includes this arca. <br /> <br />Given the above caveats. the estimated first season costs of implementing the nc\.... <br />programs and upgrading the existing programs are provided in Table 6. <br /> <br />Table 6 Estimated I'ro~ram Cosls <br /> <br />STATE New PROGRAI\.I upgradcs to cxisting total costs <br /> Costs Programs <br />AriJ:Ooa S985.000 SO S985.000 <br />Colorado $2.350.000 $1.475.000 $3.825.000 <br />Utah $1.050.000 S645.000 $1.695.000 <br />Wvoming $460.000 SO S460.000 <br />Total Cost $4.845.000 S2.120.000 S6.965.000 <br /> <br />Informalion from Table 6 can he compared to the total estimated :uJdilional <br />stn'amflow that mi~ht he produced in the four slates due to cloud seeding on an annual <br />
